Product details

Active production, AEC-Q101 qualified — BOM-fit decision

The 1.5SMC180AHE3/9AT: The -65°C to +150°C operating junction range covers under-hood thermal extremes and cold-crank events.

Clamping parametrics and pulse handling

The 154V reverse standoff voltage means it stays transparent on a nominal 154V rail and only conducts when a transient exceeds that threshold. Single unidirectional channel — one diode per package. The DO-214AB (SMC) surface-mount footprint (also designated SMCJ) mates with standard reflow profiles and is compatible with automated pick-and-place.

Sourcing and compliance posture

The series name TransZorb® is Vishay's registered trademark for its silicon-avalanche TVS family.
